This is a short video I took while in Yellowstone in February. It's of the Mollies wolf pack and shot in the Little America area. I used the D3S and Nikon 80-200 lens. It was completely dark. At the time, the Mollies had wandered north from the Pelican Valley to look for better hunting. They happened to be really close to the Lamar, Agate, & Blacktail packs.
